Fe is the basis.
According to GOST 1585-85, the limits of manganese content in castings are established depending on the thickness of the casting wall: wall thickness 5-10 mm - 7.50-8.50% Mn; > 10-20 mm - 8.50-9.50% Mn; > 20-30 mm - 9.50-10.50% Mn; > 30-40 mm - 10.50-11.50% Mn; > 40-60 mm - 11.50-12.50% Mn.

Technological properties
| Name | The value |
|---|---|
| Microstructure | Perlite or pearlitic-ferritic. Graphite: a form - ПГф1, ПГф2, ПГф4, ВГф5; size - ПГД15 - ПГД180; distribution - ПГр1 - ПГр3. Austenite: after school - at least 80% of the field section in the cast condition - not less than 45% of the field sections. Carbides: after school - time should not exceed 8% in cast condition - no more than 25%. |
| terms of Use | The use of castings made of cast iron notificationname in friction requires careful installation, providing the pair of the friction surfaces and the absence of bias; continuous lubrication, permitting true and significant heating of the friction units; increase of the gap compared to the established bronze 15-30%, in the presence of significant heating osetreni in the work - up to 50%; running at idle and progressively higher loads. At a pressure of P≤20.0 MPa sliding speed V must be ≤1.0 m/s and the product P·V ≤ 20.0 MPa·m/s At a pressure of P≤30,0 MPa sliding speed V must be ≤0.4 m/s and the product P·V ≤ 12.5 MPa·m/s. |
